`ALBERT BETTELEY, or BosToN, Massacrnismr"s,`f,` i Y l HorsrInG-MACHINE;

y specification of Letters patent No. 26,469, uafgedfij@fainter` ee, i859 Be it known that I, ALBERT` Bnrrnnnr, of

Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in ,Elevators to` be Used in Hotels c and other `Places for Raising and Lowering Persons, Goods, &c.;

and I do hereby declare that the following, taken in connection with the accompanying drawings, which form a part of this speci-` ication, is a description thereof so `full and exact as to enable those skilled in the `art-to practice my invention.

The object I have had in view, in `con-` structing this elevator has been the prevention of accidents more or less liable to occur in the use more particularly ofhotel elevators, which accidents may and are likely to happen from `various causes, such` as open-` ing, or leaving open, the door of a car,while the car is rising or descendingfor` from the car not stopping when desirable Aat the1right position to allow passengers to leave the car, or to enter the same,or from `persons `at other stations starting the car as they are apt to do when it is stationed at some` land ing to allow of theegress or ingress of passengers. Very great care and vigilanceare necessary in the common method of operating theseelevators, to prevent accidents arising from these causes, and I have therefore applied several automatic contrivances to be operated bythe ascent or descent of the car, which add very much to the safety of this `method of rising and lowering, diminish` ing the trouble and care otherwise necessary in their use.

The invention consists, first, in an arrangement of mechanism, whereby the opening of the door leading from the car, shall cause the immediate stopping of the car, providing of course that the door is opened, while the car is ascending or descending; second, in a method of causing the car to stop automatically at each or either landing, in order that passengers may enter or leave the car, the car being also prevented from being moved or started by persons at other stations, whenever it has been stopped by opening `of its door or at one of the landings.

The invention is fully illust-rated in the accompanying drawings, wherein- Figure 1, denotes a view of the interior of the car, showing the side thereof on which the door is situated, and one of the sides adjacent to said door. Fig. 2, is a horizontal PATENTOFFI i `Gr, and under these circumstances, the shipsectionof such por fons` y hecarh c adjacent sides to they vatchway `sliowiiifngvw the mechanism appertaining tomy, inventio in top view.` e y c, il, 111l the Said drawhsswhereveffseeh, A, denotes thel car, or transporting chamber ,"B, the hatchway, through` whichthe "r guided in its ascent and desoentinfthej su manner;` C, the door; leadingfrom h` D,@oppositedooaleadagsw g several landings, ivhicliis to be larly provided with c a ,i door" to `be :locked an unlocked by a passing car;` c

'Ihe camis `so made asto keep` the lever grasping the rope, wheneverwand 1,05 however much the-door may be open`ed,the` 1 l car being` therebystlopped untihwher` (atmi, i such time as it maybe again closed) ,thecon-v` 1 e ductor Orotherperson, can throwback the` belt by moving the shipper `rope E, in` oneli direction orthe other and thereby start the car. Thus the opening of theidoor, maybe t used as a means of stopping the car when desirable, although my invention particularly relates to stopping the car from the accidental or careless opening of it.

K, is a spring lever hung and turning upon a fulcrum d, and bent around and having a spring e, fastened to its lower arm f as seen in Fig. l. The arm f, rests and is supported upon a shelf g, being generally kept thereupon by a supporting pin p. The upper arm of the lever K impinges against the outer arm of the lever Gr, which it operates as before described to pinch upon the rope. t A spring z' is attached to the outer side of the car, as seen in Fig. 2, one end thereof being bent around and extending through the side of the car, so as to come into or nearly into contact with the side of the lever K. A stationary cam projection m, is placed opposite thereto on the side of the hatchway, the cam being so placed that as the car passes up or down by it, the spring z', shall strike against, and be forced in by it, thereby pushing the lever K, from its shelf, which l (if its pin h is removed) being drawn down by its springs, actuates the lever G.

Now I so place the cams m, and spring i, that they shall come in contact just as the door D of each hatchway or landing, comes opposite to the door C, of the car, or in positin to allow, when the said doors are opened, free passage through them. When the car in its ascent or descent, comes to a landing, and the spring and cam into contact, the spring as before stated will push the lever K, from its seat, thereby causing it, (providing the pin h, has been removed) to actuate the lever G, and cause the car to be stopped, just as it is stopped at other times by the opening of the car door as before described. Before the car is again started, the conductor or some person therein, lifts the arm f of the spring lever upon its seat, g, and so as to release the shipper rope from pressure, when the car will be free to be set in-motion by pulling the shipper rope as will be readily understood.

Thus it will be seen that the car can the car will be arrested without Yfurther effort or attention. And it will be further seen that while thus stationary ata landing, no person above or below can start the, car, as the pressure on its shipper cord remains until some person in the car removes it, when by pulling the shipper rope, the car is again set in motion.

I would remark that though I have described thus particularly the several mechanical devices for carrying out the purposes above set forth that I by no means intend to confine myself to such devices, but to vary them as circumstances or experience may dictate or require, using any method for arriving at the same results, which shall be substantially the same, or which do not depart from the spirit of my invention.

I claim therefore: Y

l. Bringing the car to a stop whenever (while in motion) its door may be opened, by causing the shipper rope to be pinched or held substantially as above described.

2. The arrangement substantially as above specified for causing the car to be stopped at proper times or places, said arrangement consisting of cam m, spring z', levers K, G, operating together Vand upon the shipper cord.
